A volcano is an opening in the crust of a planet, through which molten magma, ash, and gases can escape.[1]

In 79 AD, Zaccaria Innocenti made inappropriate use of the Tarantallegra spell, "conjuring a 'dance'" inside the volcano Mount Vesuvius,[2] which possibly triggered the major eruption it had that year.[3]

Ron Weasley forget that Io is the moon of Jupiter that has volcanoes on an Astronomy essay he wrote in 1995.[4] Hermione Granger caught this mistake and Ron proceeded to scratch out the erroneous sentence.[4]
